Continuum of asthma management. Inhaled corticosteroids (ICSs) should be introduced as initial maintenance treatment, even with symptoms experienced less than three times per week. Although less effective than low-dose ICSs, leukotriene receptor antagonists (LTRAs) are an alternative for patients who cannot or will not use ICSs. If control is inadequate on low-dose ICSs, identify the reason (or reasons) for poor control, and if indicated, consider additional therapy with long-acting β₂-agonists or LTRAs. Severe asthma may require additional treatment with systemic corticosteroids. Asthma control and maintenance therapy must be regularly reassessed.
